d1-server with digital outputs Totaldac d1-single front

The music server allows to listen to all your music from a single storage and with the best possible sound.
The d1-server could also be called network player or streamer.
The d1-server has been designed with the same target as for the Totaldac DACs, to deliver the best sound.
The d1-server is integrated in a d1-digital reclocker which guarantees a low jitter and a low noise with digital preamplifier functionalities such as several auxiliary digital inputs, all de-jittered by the internal reclocker.
DSD files can be read and are then sent in DSD DoP format or transformed to pcm 176KHz/24 to the spdif and AES-EBU outputs.

"totaldac + Roon = Happiness
What do you get when you combine a totaldac and Roon and Tidal HiFi? Endless enjoyment."

About the server functionality, tested with the d1-integral-headphone. Michael Lavorgna, AUDIOSTREAM (Stereophile)
"the only impression I ever seem to get from totaldac products is pure musical pleasure.
I am sent on a journey through my music, engaged and relaxed with no fatigue or worry."
Sonny Trigg, inearspace
"These d1-server + d1-dual or d1-tube set-ups attained a level for PCM and DSD which Id not heard before.
The d1-server and its reclocker are absolute key points to get something quite magic at the end.
After this review, the prize "Grand Frisson" of Audiophile Magazine is obvious:
- for the sound quality
- for the turn-key network solution with very easy set-up
- for the flow of innovations inside"
Thierry Nkaoua, Audiophile-Magazine and 6moons

Totaldac d1-single front
The d1-server has digital outputs exclusively, spdif and AES-EBU, so compatible with most DACs.
It is controlled from a computer or an Ipad tablet.
The music storage is external to allow a maximum of flexibility. It can use ethernet discs (NAS) or USB dongle or USB disc (new) .
The music files are ripped or copied from another computer to the external discs.

Totaldac d1-server schematics

Embedded reclocker interfaces:
-192KHz asynchronous Xmos USB, RCA, optical and AES-EBU digital inputs, selectable from a remote control.
-44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz and 192KHz, 16 to 24 bit formats supported on all inputs except 96KHz max for optical input.
-DSD (DoP standard) supported on the USB, AES-EBU and spdif inputs.
-an custom DSD to 176.4KHz/24 pcm can be activated or disactivated from the remote control.
-AES-EBU and spdif (RCA or BNC) digital outputs, only one of these outputs must be used at the same time.
-embedded custom clock with anti-jitter FIFO memory.
-69bit digital volume control, adjusted by a remote control and an OLED display. The remote control receiver can be disabled by a switch to dedicate the remote control.
-bit perfect signal path when the volume is set to maximum (0dB).
-phase polarity selected by remote control.
-display switched off by remote control or automatic.
-external power supply to minimize the noise.
-aluminium and PMMA enclosure.
-power consumption 20W.
-dimensions: height 110mm, width 360mm, depth 290mm.
-power supply dimensions: height 65mm, width 122mm, depth 180mm.
-weight: 4kg.

Computer type interfaces:
-1 ethernet port which must be connected to a Wifi/ethernet router for the control from an Ipad via WIFI.
It gives also access to the distant network hard discs (NAS).
Those who wish can use a computer without WIFI as a remote control via ethernet instead of a tablet via WIFI.
-1 USB2 port as an audio output to the embedded reclocker.
-1 USB2 port for an optional USB dongle or USB disk.

The d1-server is composed of 5 key elements:
-the Totaldac d1-digital reclocker. It generates the spdif et AES-EBU, recognised for its sound quality.
-The ARM based mini computer, a tiny and very low consumption computer, which generates much less electromagnetic pollution than a bigger computer.
This mini computer is completely shielded. Its software can be updated by simply changing the microSD card easily accessed on the back panel.
-A 5V ultra low noise power supply, herited from the d1-dual DAC design.
The music library is usually copied and organised in the NAS or in the USB disc using a Windows or MAC computer.
-The Totaldac USB cable/filter or gigafilter, recognised and tested in many different environments (this is an option).

compatible applications:
RoonReady (certified by Roon)
Soundirok for Ipad or Iphone
MPdroid, M.A.L.P. or MPD Control or Soundirok for Android
upnp/DLNA, for example for Jriver or Minimserver or Mconnect or BubbleUPNP or Spoticast
Streaming such as Qobuz and Tidal via Roon or upnp or Airplay

What are Roon and RoonReady?
Roon is the most engaging, enjoyable way to browse your music.
Being RoonReady means that Totaldac network players transparently discover and connect to Roon, with no network configuration, with bitperfect delivery of audio to your dac.
Together, Roon and Totaldac deliver the power, flexibility, and performance benefits of networked audio, with the easiest setup and highest reliability available.

Available options:
-silver massive aluminium front panel.
-115V or 100V power option.
-BNC coaxial digital input and output instead of RCA.
-custom made conical feet, made of anodised aluminium, on demand only.
-dedicated power supply for server board.
